Description
PORTABLE TERMINAL DEVICE
ANI) METHODS THEREFOR
BACKGROUND OF THE INVENTION
The present invention relates to a portable terminal device, particularly a wireless portable terminal device, to an outgoing call control method, and to a data transfer method.
Portable terminal devices and mobile phones, which are generally referred to as a' PHS" and "cell phone," are small and lightweight, and are provided with various additional functions, and they have made remarkable progress and are practically replacing the conventional cable telephone system.
Mobile phones have not only a basic communications function, but also a telephone book function, an outgoing call history entry function, an incoming call history entry function, a memo recording function, etc. Generally, a user's personal data are stored in a memory in advance to carry out the above functions. And then, the user, by handling the operation button(s), can fetch the contents of the memory at any time.
Moreover, mobile phones typically have a locking dial function to prevent billing the owner of the mobile phone for an unauthorized outgoing call made by a person other than the owner when the mobile phone is stolen or lost. The function also prohibits them from browsing personal data stored in the memory.
This dial lock capability can be set by the owner of the mobile phone by registering his or her password in the mobile phone, and pressing a specific operation button, e.g.,, pressing a function key for a prolonged time. The dial lock can be released by inputting the registered password, and pressing the specific operation button, e.g.,, pressing the communications button for a prolonged time.
Although an unauthorized outgoing call or unauthorized browsing of personal data can be almost completely deleted by constantly using the above mentioned dial lock, and releasing the lock each time communications are started, setting a dial lock and releasing the lock each time communications are started is ti,lle-consull.ing, and therefore not perfolllled. Therefore, when a rllobile phone is stolen or lost, there is the possibility that a person other than the owner uses the mobile phone without authorization, thereby causing financial damage and unauthorized browsing through personal data.
Therefore, as disclosed in Japanese Patent Laid-Open No. 2000-
151798, a signal code for controlling outgoing call and for prohibition against browsing personal data is entered in advance in the body of a mobile phone. The lost mobile phone is called from a subscribed phone or another mobile phone through an exchange system. A request code is transmitted with a communications circuit established, and outgoing call control is executed and memory data is locked when the signal code of the lost mobile phone matches the request code.
Simultaneously, the personal data is pulled out by the equipment such as the personal computer, etc. connected to a telephone line as necessary, and then the personal data stored on the lost mobile phone is deleted.

The above mentioned case can also be applied not only to a lost mobile phone, but also to all portable terminal devices such as mobile personal computers or personal digital assistants having the communication 5 functions.
The conventional portable terminal device can lock an operation key or personal data to prevent an unauthorized use or unauthorized leakage of personal data by a third party using stolen or lost equipment only after a 10 communications channel circuit is established. That is, the above mentioned process can only be performed when an answer is returned in response to a call to a stolen or lost portable terminal device. However, it is not likely that a third party will answer the call to the stolen or lost 15 equipment. Therefore, the condition of possibly issuing an unauthorized outgoing call and browsing personal data still continues. As a result, a countermeasure is only to issue a request an exchange center to reject an outgoing call, and to perform the outgoing call rejection by the exchange 20 center, thereby having no means for prohibition against browsing personal data.

By periodically receiving the control channel, the presence/absence of a request is analyzed, thereby performing control with higher reliability. That is, when a communications channel circuit is used in the remote control, the control can be interrupted on the base station side depending on the state of the communications traffic. For example, it can be interrupted during the transfer of personal data. Using a control channel, such interruption cannot occur, thereby reserving a circuit with high reliability.
Since remote control is performed by using a control channel without remote control using a communications channel circuit, it is not necessary for an answer from the third party who now holds a stolen or lost equipment, and
unauthorized outgoing calls or unauthorized browsing of personal data can be immediately prohibited.
Accordingly, the present invention can provide a portable terminal device capable of performing outgoing call control on a stolen or lost portable terminal device with high reliability without requesting an unauthorized user to return an answer or requesting an exchange center to reject an outgoing call, and capable of prohibiting the unauthorized browsing of personal data without requesting an unauthorized user to return an answer.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other aspects, features arid advantages of the invention will become more fully apparent from the following detailed description taken in
conjunction with accompanying drawings. In the drawings: FIG. 1 shows a configuration of an entire system of a portable terminal device according to an embodiment of the present invention; FIG. 2 is a block diagram of a circuit of a central portion of a lost mobile phone 1 shown in FIG. 1; FIG. 3 is a flowchart of the operation of a control channel of the lost mobile phone 1 shown in FIG. 1; and FIG. 4 is a flowchart of the detailed operations of a data transfer process shown in FIG. 3.
DETAILED DESCRIPTION OF THE EMBODIMENTS
Hereinafter, each embodiment of the present invention will be described in detail with reference to the drawings.
An embodiment is obtained by applying the present invention to a mobile phone, and the entire configuration will be described below by referring to FIG. 1. A lost mobile phone 1 can perform normal communications during power-
up, and can be set in a state of browsing telephone book data and incoming/outgoing call history data by a key operation.
The portable terminal device is configured to communicate with a number of mobile phones through an antenna 4 provided in a base station 3 connected via cable to a public line network 2. Practically, the equipment is configured to include radio means capable of communicating communications channel data with base station 3, and capable of communicating control channel data with the base station 3 at an appropriate timing independent of the communications channel data.
On the other hand, a data storage system 6 is connected to the public line network 2 through a modem device, which is not shown in FIG. 1. That is, a personal computer 7 operated by a user 5 is connected to the public line network 2.
At a result, communications with the personal computer 7 and both the base station 3 and the lost mobile phone 1 can be established. The personal data can be pulled out from the lost mobile phone 1 (as described later) is temporarily stored in the memory in the personal computer 7. A substitute mobile phone 8 is connected through a connection cable 9, thereby transferring the personal data to the substitute mobile phone 8.
The circuit of the portable terminal device (lost mobile phone 1) embodying the present invention is configured as shown in FIG. 2. That is, the equipment is provided with a conkrol unit 10 for combining and controlling the
operation of the mobile phone 1, and a radio unit 12 having an antenna 11 is connected to the control unit 10.
The radio unit 12 forms the central portion of radio means capable of communicating communications channel data with the base station 3 through the antenna it and the antenna 4, and communicating control channel data at an appropriate timing independent of the communications channel data.
A display unit 13 connected to the control unit 10 is configured to include display means capable of displaying a basic call functions, and displaying the contents of outgoing call control and/or data locking when they are performed.
The equipr.er.t data specifying the equipment (lost mobile phone 1i, and personal data 16 formed by telephone book data, outgoing call history data, incoming call history data, memo data, etc. is included in a memory block 14 connected to the control unit 10. The transfer permission data for permission of a request to transfer the personal data 16 is registered in the memory block 14, and permission data 15 in which data for permission of a request to lock a dial and memory is registered is included in the memory block 14. Thus, the central portion of the registration means can be configured.
received data analysis unit 17 connected to the control unit 10 forms determination means. Practically, the determination means compares transfer request data with the transfer permission data of the permission data 15, and determines whether or not they match each other when the control channel data received by the radio unit 12 includes the transfer request data. If the determination means detects a matching result between the transfer request data and the transfer permission data, then control means has the control unit 10 control the radio unit 12 -
_3 to transfer the personal data 16 to a predetermined destination. The personal data 16 will be transferred to the personal computer 7 of the data storage system 6. The control means also controls the radio unit 12 through the control unit 10 to exert control over an outgoing call when a matching result is detected between the outgoing call control request data and the outgoing call control permission data.
An arrow, shown in FIG. 1 by dotted lines from the user 5 toward to the antenna 4, indicates an electric wave path for remote control of the outgoing call control, prohibition against browsing personal data, and pull-out of personal data on the lost mobile phone 1. User 5 accomplishes this by using another mobile phone.
This operation will be described later, and the operation of the personal computer 7 connected to the public line network 2 at the time of performing the remote control will be described below by referring to the flowchart shown in FIG. 3.
The operations described below are performed on the assumption that the lost mobile phone 1 is located in the position where the lost mobile phone 1 can receive an electric wave transmitted through the antenna 4, and that the lost mobile phone 1 is powered up and set in a reception wait state. The outgoing call control operation and the data transfer operation are performed by obtaining data when the control channel data transmitted at an appropriate timing from the base station 3 through the antenna 4 is received by the radio unit 12 of the lost mobile phone 1 at S1. At S2, the received data analysis unit 17 analyzes the data, and then, at S3, the control unit 10 acts accordingly.
At S3, it is determined whether or not the received control channel data includes a request to transfer the personal data 16 or a request for the permission data 15. If there are no such requests (NO), then the process terminates.
- 11
On the other hand, if it is determined YES at S3, then at S4, it is determined whether or not there is memory lock permission data. If there is the permission data (YES), then control is passed to S5, where the request to lock the memory block is issued. Control then passed to S6, where it is determined whether or not there is personal data transmission permission. If it is determined NO at S4, however, control proceeds directed to S6. At S6, it is determined if there is permission to transfer personal data. If it is determined YES at S7, then a request to start transferring person data is issued. Otherwise, if it is determined NO at S6, control passes to S8, and the data transferring process is performed after proceeding to next S8, thereby terminating the process.
As shown in the flowchart in detail in FIG. 4, it is determined whether or not there is a request to start transfer of the personal data 16 in S9. If there is the request (YES), then control passes to S10, where the telephone book data, outgoing call history data, incoming call history data, and memo data stored in the personal data 16 is read by the control unit 10 and transmitted through the antenna 4, the radio unit 12 and the antenna 11 to the memory of the personal computer 7. The data is temporarily stored in the memory of the personal computer 7. Control is then passed to S1 1.
It is determined at S11 whether of not there is a request to lock the memory block 14. If there is the request (YES), then control is passed to S12, and the memory block 14 is locked, thereby terminating the process.
If it is determined in S9 that there is no request to start transferring the data (NO), then the above mentioned S11 and S12 are not performed.
- 12
Thus, outgoing call control is executed on the lost mobile phone 1, the unauthorized browsing of personal data is prohibited and the personal data is pulled from the lost mobile phone 1. Therefore, the third party having the lost mobile phone 1 cannot issue a call, and cannot browse personal data, thereby completely preventing an unauthorized use and unauthorized leakage of the personal data by the third party.
Furthermore, since the above mentioned preventing process is performed using the control channel without establishing a circuit of a communications channel, the process can be realized without waiting for a response to a call to the lost mobile phone 1. That is, it can be realized only if the lost mobile phone 1 ham been powered up and is located in the service area of the antenna 4, thereby realizing a perfect countermeasure.
If the lost mobile phone 1 has not been powered up yet, then it is powered up and simultaneously a call is automatically issued through a control channel circuit. Therefore, in response to the call, the base station 3 prepares data to remotely control the outgoing call control, the prohibition against unauthorized browsing of personal data, and the retrieval of personal data in advance. As a result, when the lost mobile phone 1 is powered up, the outgoing call control, the prohibition against browsing personal data, and the retrieval of personal data can be simultaneously performed.
On the other hand, as an example other than the above mentioned case in which the remote control is performed on the lost mobile phone 1 through the public line network 2 and the base station 3, the user 5 can perform remote control on the base station 3 using a mobile phone. In this case, a control code for execution - 13
of the outgoing call control, the prohibition against browsing personal data, and the retrieval of personal data is transmitted from the user 5.
In this case, the retrieval of personal data can be directly performed if there is a sufficiently large memory capacity of the equipment. If there is no sufficiently large memory, the data is temporarily stored in the base station 3, and is fetched later using a personal computer or other communication devices By allowing the personal computer 7 storing the personal data 16 fetched from the lost mobile phone 1 to be remotely controlled to be connected to the substitute mobile phone 8 with the connection cable 9 connected through a predeten.n.ined interface circuit Ad to execute the edit so^.,are of the data of the mobile phone built in the personal computer 7, the personal data 16 of the lost mobile phone 1 can be transferred as is in the substitute mobile phone 8, or in an edited state.
As a result, the personal data can be retrieved regardless of whether or not the lost mobile phone 1 is practically held at hand.
In the explanation above, the portable terminal device (lost mobile phone 1) comprises a first control means for exerting control over an outgoing call by controlling the radio means when a matching result is detected between the outgoing call control request data and the outgoing call control permission data. The portable terminal device comprises a second control means for transferring the personal data to a predetermined destination by controlling the radio means when a matching result is detected between the transfer request data and the transfer permission data. However, the portable terminal device can also be configured by comprising one of the first control means and the second control means.
- 14
The outgoing call control on the portable terminal device can function as software by directly prohibiting a call issuing operation, or can perform indirect prohibition by providing operation lock means for suppressing the key operation of issuing a call. Similarly, the prohibition against browsing personal data can function as software by directly prohibiting a browsing operation, or can perform indirect prohibition by providing data lock means for suppressing the key operation of browsing the personal data. The personal data pulled out from the portable terminal device (lost mobile phone 1) can be stored in the personal computer 7, directly stored in the substitute mobile phone 8, temporarily stored in the base station 3 and then fetched later, etc. Furthermore, the permission data registered in advance in the lost mobile phone 1 for determination of the outgoing call control, the prohibition against browsing personal data, and the retrieval of personal data can be configured by including a telephone number and/or the equipment number or by a password at the discretion of the user.
Additionally, when the outgoing call control and/or data lock is perfonned, the contents can be displayed indicating "this phone is not available" or "please contact the owner XXX" on the display unit 13.
Obviously, numerous additional modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
